Trane 5TEM4D05AC41SA – 42,000 BTU 3.5 Ton R-454B Convertible Constant-Torque Air Handler

Deliver dependable indoor comfort and efficient airflow performance with the Trane 5TEM4D05AC41SA, a 3.5-ton convertible air handler engineered for modern residential HVAC systems. As part of Trane’s 5TEM4 series platform, this air handler integrates a constant-torque ECM blower motor, all-aluminum plate-fin indoor coil, and insulated galvanized steel cabinet construction designed to support reliable heating and cooling operation across a wide range of residential installation environments.

Constant-Torque ECM Blower Motor Performance
The 5TEM4D05AC41SA utilizes a direct-drive centrifugal blower powered by a constant-torque ECM motor engineered to provide efficient airflow delivery and consistent indoor comfort. The blower operates at approximately 1050 RPM and provides nominal airflow of approximately 1,400 CFM, helping maintain balanced air distribution and efficient HVAC system performance in medium-to-large residential applications.

3.5 Ton Air Handler Capacity Platform
Model nomenclature identifies this unit as part of the 3.5-ton air handler capacity platform, supporting nominal system capacities ranging from approximately 36,000 to 48,000 BTU. The unit operates on 208/230V, single-phase, 60 Hz electrical service, allowing compatibility with a wide range of matched outdoor air conditioning and heat pump systems designed for R-454B refrigerant operation.

All-Aluminum Plate-Fin Indoor Coil
The indoor coil features an all-aluminum plate-fin design engineered for reliable heat transfer performance and enhanced corrosion resistance. Designed for R-454B refrigerant systems, the coil utilizes a factory-installed thermal expansion valve (TXV) to regulate refrigerant flow and support efficient operation during both heating and cooling cycles.

Convertible Multi-Position Installation Design
The 5TEM4 series air handlers incorporate a 4-way convertible cabinet design, allowing installation in upflow, downflow, horizontal left, or horizontal right configurations. This flexibility allows the unit to be installed in closets, basements, crawlspaces, utility rooms, or attic spaces depending on the building layout and HVAC system design.

Durable Insulated Cabinet Construction
The cabinet features galvanized metal construction with captured foil-faced insulation rated at R-4.2, helping improve system efficiency while reducing cabinet condensation and operational noise. The cabinet is engineered to maintain 2% or less air leakage, supporting consistent airflow and overall HVAC system performance.

Draw-Through Airflow Design with Horizontal Drain Pan
The air handler utilizes a draw-through airflow configuration that promotes consistent airflow across the indoor coil for improved heat transfer efficiency. A factory-installed horizontal drain pan with a 3/4-inch NPT condensate connection supports reliable condensate drainage during cooling operation.

Electric Heat Compatibility for Supplemental Heating
The 5TEM4D05AC41SA supports field-installed electric resistance heater kits from the Trane BAYHTR series, allowing optional supplemental electric heating when paired with heat pump systems or used in electric heat applications. Multiple heater capacities are available to accommodate various installation requirements.

Large Cabinet Design for Increased Airflow Capacity
The unit features cabinet dimensions of approximately 51.3 in. H × 23.5 in. W × 21.1 in. D, providing increased internal airflow capacity while maintaining a footprint suitable for residential mechanical spaces and utility installations.

Engineered for Reliable Residential HVAC Performance
Ideal for medium-to-large residential HVAC systems, the Trane 5TEM4D05AC41SA air handler delivers dependable airflow performance, durable coil construction, and flexible installation capability in a constant-torque indoor platform designed for efficient comfort and long-term reliability.
